Well, I can't call tu stupid o anything, because I had an online relationship with a boy on here when I was fourteen. But from experience, I'm going to bluntly tell tu to not go for it. Online relationships are just never successful. There was nothing wrong with the guy I dated (except he kept some things from me until a pretty bad time, but I didn't dwell on that), and I remained friends with him after we broke up (but I haven't talked with him lately). But, it's just not someting you'd want to do.
And I was lucky to have my online bf be a very sweet person. tu could easily have an online BF that is Jack McClellan in disguise (

Don't go for it.
